Is this the right machine for you?

Best for:

  • Grout, textured tile, quarry tile and uneven floors: roller brushes reach low spots
  • Floors with small debris: the brushes sweep it into a tray while they scrub, so you often skip the sweeping step
  • Schools, healthcare, retail, food service and offices: 60 dB(A) in eco mode (TASKI figure)

Not a good fit for:

  • Round pads and pad polishing: this machine uses roller brushes and pad rollers
  • Large debris such as cans, bottles or pallet scraps: sweep first
  • Carpet
